ABSTRACT:
A method for tracking seismic events such as boundaries of formation layers of earth formations is disclosed. Especially adapted for tracking such events in a two-dimensional slice of 3-D seismic volume data, the method begins by designating a starting data point on the seismic event. The method tracks such event through the grid of data by sequentially establishing areas or "tiles" of data about the starting point. The tiles are defined by data points of the grid. Each of the data points is then tested to see if it meets an acceptance criterion for the seismic event. Such data points of the tile are stored as identifying the seismic event only if certain of the data points of the tile pass the acceptance citerion. Next, each of the data points of a previously accepted tile are used as a starting data point about which a new tile is defined. The process is repeated until no more tiles are available for testing. The accepted data is then displayed so as to distinguish the accepted data from other data of the grid thereby identifying the seismic event to seismic interpretation specialists.
